The ANSI/ISA-95 (ISO 62264) standard is a key concept driving the implementation of Industry 4.0 in industry. It is a backbone of the Reference Architectural Model for Industry 4.0 (RAMI 4.0) and describes the objects, models and activities on operations management hierarchy level (Level 3). A major model described in the standard is the Planning model, in which is described that the planning activities rely on requirements of personnel, equipment and/or material. Also, a general concept in all models, described in the standard is the process segment that may refer as a combination of specific equipment/asset (with enough capability), a material (with specific quality) and/or a person (with proper qualification). In this article the Segment Dependencies impact on Capacity and Planning models is examined and some conclusions are made.
